Hi All, Recently I found this orange Disco growing with Marchantia and mosses in a damp, shady corner close to farm buildings. Details are as follows:
Ascomata 4-7mm. Shallow bowl shaped when young, becoming discoid, sometimes with a lobed margin. Excipulum downy with hyaline/whitish hairs. Hymenium orange.
Ascospores ellipsoid, smooth, with granular contents, without guttules, 31-37.5x16.5-18.5.
Asci 245-305x27.5-35.
Hairs hyaline, thick-walled, septate, sometimes with mucilaginous deposit, 190-500x7.5-12.5,Â
some with a swollen basal cell. Marginal hairs wider, ones further down more slender and grading into rhizoids.Â
Paraphyses very pale under microscope, swollen to 6-10, septate.Â
Excipulum more or less a Textura Globosa with ellipsoid, thick-walled cells with walls up to c3 thick.
Asci and ascospores dextrinoid in Melzer's.
This taxon appears to be bryophilous/parasitic with rhizoids attaced to living mosses and Marchantia. I have considered Neottiella, Cheilymenia and Octospora but none seems to quite fit.Â
Seasons Greetings,Â
Charles.

Hi Charles,
this looks like Octosporopsis nicolai.
Best,
Björn

Re : Neottiella?
The liverwort should (then) be Lunularia cruciata. I do not see the "Brutbecher" that should be lunate and not circular like in Marchantia.

Hi Bjorn and Lothar,Â
Many thanks for your rapid responses. I've added a couple more photos, one showing more typically shaped ascospores (in the other photo they were a bit wide). Also a view of the margin. I've never heard of Octosporopsis so that's interesting! I think the liverwort is Marchantia although I'm not an expert.Â
Best wishes,Â
Charles.

Hi again,Â
I've attached a photo of the liverwort which I think is Lunularia.Â

Re : Neottiella?
yes, Charles.
O. nicolai is specialised to Lunularia, as I wrote.
I know it from Portugal and Spain.
By now I did not find it in Germany, although Lunularia grows there also.
Yours, Lothar

Hi Lothar,Â
A pleasing record; there are three previous ones for Britain according to FRDBI.Â
